You have to have an oil cooler, im not sure if the eitms can be used with the 120 or not, the fan can be added. I went to a concert with my stock 96 and we were stop and go for an hour. the heat was noticeable, it got hot, however, the engine didnt miss a beat, i was nervous. It seams they can handle more heat than perceived. I look at it like this, buy the already built hd engine, sell my stocker and that makes the upgrade much less than doing a kit that relys on the engine techs ability to build it right.What I can't understand is this. I can't stand still for more than 90 seconds without my "96" overheating. How on earth do you keep a "120" cool in the middle of the summer? What do you do in stop and go traffic. The size of the combustion chamber has a (huge) direct relationship to produced engine heat. Without changing the way to sink or get rid of this heat, what do you do?
A rich mixture will only do so much. Without air movement I can't see how the really big engines get through a summer day with everyday traffic problems, those really long red lights,etc.
